Rope Types and Materials

Modern yacht ropes are made from synthetic materials. The most common are: Polyester (Terylene/Dacron) — strong, low stretch, UV-resistant, used for sheets and halyards. Nylon (Polyamide) — very strong with high elasticity, ideal for anchor warps and mooring lines because it absorbs shock. Polypropylene — inexpensive, lightweight, floats, but weakened by UV and relatively low strength; used for safety lines.

Dyneema and Spectra are ultra-high-strength, low-stretch fibres used in high-performance halyards and sheets. They are light and extremely strong but more expensive and can be slippery if not handled correctly.
